Gowanda’s 121KM2502HM is a horizontal mount high efficiency standoff toroidal choke designed for demanding applications. With a weight of 12 grams and compact dimensions of 22.86 × 22.86 × 12.7 mm, this component is part of the KMHM series and features a surface mount technology (SMT) for ease of integration. It is classified under the COTS+ application grade, ensuring high reliability and performance. The choke offers an inductance of 25 µH, a direct current resistance (DCR) of 0.017 Ω, and a self-resonant frequency (SRF) of 5 MHz. It supports a current rating of 6.34 A DC, with incremental current limits of 3300 mA DC for a 10% change and 5700 mA DC for a 20% change. The component has a tolerance of ±10% and features a Pb termination type with a Sn63Pb37 finish. It operates efficiently across a wide temperature range of -55°C to +130°C and has a moisture sensitivity level (MSL) of 1, making it suitable for various environmental conditions. The product is available in bulk packaging.
